Version

Media3 main branch

More version details

Video track produces no frames for decoding.

Upon deeper investigation of H264Reader#endNalUnit it seems that outputSample branch is never executed.

The stream does not contain any AUD NAL units, and neither is detectAccessUnits set to true.

The NAL units in the stream are as follows:

SPS -> PPS -> SEI -> IDR -> NON_IDR -> NON_IDR etc.

Devices that reproduce the issue

Reproduction steps
